To all whom it may concern..A l

Be it known that I, PATRICK FrrzGrBnoNs, of Oswego, in the county of Oswego, in the State of New York, havey invented new and useful Improvements in Fluo-Cleaners, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to improvements in iue cleaners, and has for its object the production of a simple, practical, and e'ective device for accomplishing the desired result, which consists of a minimum number of parts; and to this end it consists, essentially, in a shank, a pair of spring sections having'corresponding extremities secured to the shank and their opposite extremities independently movable, and provided with interlocking ends, and engaging cleaning sections secured to the opposite extremities of the spring sections and `having their outer faces formed with rounding shoulders. It furthermore consists in the detail construction and arrangement of the component arts.

In describing this invention, reference is had to the accompanying drawings, forming a part of this specification, in which like letters indicate corresponding parts in all the views.

Figure 1 is a top plan of my improved flue cleaner. Fig. 2 is a longitudinal vertical sectional view taken on linel 2--2, Fig. 1. Fig.,3 'is an end elevation of theflue cleaner; and Fig. 4 is a transverse sectional view taken on line 4 4, Fig. 2.

A represents the shank herein illustrated as composed of two divisions a a removably secured together by screws a2. Itis evident, however, that the shank A may be of any desired form, size, and construction.

B B are normally divergent spring sections of the iiue cleaner having corresponding extremitiesb removably secured by screws as to the shank A, and as clearly seen at Figs. l and 2the ends ofv the extremities b bear against the corresponding faces of theshank division a. If desired the spring sections B B may be riveted or otherwise secured to the shank A. The opposite extremities of the spring sections B B are free and independently movable, and yare provided with ends or projections B? Badetachably engaging each other. The projection or end B2 preferably consists of a /tapering spur having rounding outer edges, and the projection B3 of a socket preferably having a tapering cutout or slot B4 therein, and formed with yielding walls B5 having rounding edges. The projection B2 is readily forced through the opening or slct B4 into the socket B3 and is free to move therein assaid socket is of greater width than the thickness of the projection B2. When desired to remove the projectionor spur B2 itis readily forced outward through the opening or slot `B4 in the socket B3 as the adjacent walls of said socket are yielding and free to move. It is evident, however, that the socket B3 may be unprovided with a cutout or slot B4 and that the projection or spur B2 may be engaged therewith longitudinally when assembling the parts of the flue cleaner.

O C' are engaging sections of the flue cleaner secured,'respectively, to the spring sections B B thereof, and as clearly seen at Figs. 1 and 2, these sections'CO are secured at one side of the ends B2 B3, which virtually form longitudinal projections from the sections C O', although formed directly upon the parts B B. The engaging sections C C may be removably secured to the spring sections B B by screws c asillustrated, or they may be rigidly secured thereto, if desired. The engaging sections C C and the spring sections readily replaced when injured or unduly worn. The adjacent faces of the engaging sections C O of the iiue cleaner are formed with recesses or grooves c c2 extending throughout the length of the section for receiving the springs B B and the adjacent edges of said sections are formed with shoulders c3 detachably engaging each other. Theengaging sections C C are preferably formed of greater thickness at their central or intermediate portions and their opposite extremities are more or less tapered, and, as clearly seen at Figs. 1 and 2, the central or intermediate portions of saidsections are each provided exteriorly with rounding transversely extending shoulders C2 separated by a groove C3.

B Bowing to their peculiar arrangement, are

accumulation not disengaged from the iiue by the preceding shoulder. The spring sections B B operate to force the shoulders G2 outwardly against the interior of the flue with sufficient force ro remove any accumup shank, spring 'sections `having corresponding lation of ordinary hardness and` thickness; and also permit the shoulders to yield in- Wardly when an undue accumulation is en- Y countered. The interlocking projections B2 edges provided with lateral B3 at the outer ends of the springs prevent the undue separation ofthe scrapingsections C C', and the engaging shoulders cat the edges of the scraping sectionsassistin resisting the strain which occurswhen one section strikes a scale in the longitudinalmovernent! of the device.

A flue cleaner of this peculiar construction and arrangement is particularly practical, et'` fective, and durable, and, as is evident, consists of a small numberof parts, and isextremely compact and-simple in construction.

Having thus fully described what I claim as new, and desire to secure by Letters Patent, is-- 1. In aiue cleaner, thecombination of a shank, spring sections havingcorresponding extremities xed to the` shank andtheir opposite extremities separated and independently movable, engaging sections fxedfto` the spring sections and having their adjacent shoulders arranged one in advance of the other and' thelr outer faces provided with transverse rounding engaging shoulders,` a

projecting socket secured to the free endof one of the engaging sections, and aprojection or spur secured to thefree end? of the other engaging section and movable within the socket, substantially asdescribed.

2. In a hue cleaner, the combination of ashank, spring sections having corresponding.

extremities removably attached to the shank, and their opposite extremities independently movable, and engaging sections fixed to the spring sections and having their outer faces provided with rounding engaging shoulders and their inner faces provided with groovesextending from end to endfor receiving the adjacent portlons of the springsections'and* formed of substantially the samewidth as said portions, a projecting socket secured tothe free end of oneofthe engaging sections, and a projection or spur secured to the free end of the other engaging section and movbltlwithin the socket, substantially as set ort 3. In a flue cleaner, the combinationof a shank, spring sections having corresponding my invention,-

interlocking` extremities fixed to the shank and their opposite extremities separated and independently movable, and engaging sections removably attached to the outer faces of the spring sections and extending laterally beyond the same, said engaging sections having their adjacent edges at eitherfside of the springs providedv with lateral interlocking shoulders arranged one in advance of the other and their ,outer faces provided with transverse roundfing engaging shoulders, substantially as described.

4. In a flue cleaner, the combination of a extremities removably attached to the shank,

Vand their opposite extremities independently movable, engagingsections fixed to the spring sections and havingwtheiradjacent edges provided'with lateralinterlocking shoulders arranged onein advance ofthe other, their outer facesA providedwith roundingengaging shouldersl and` their inner faces provided` With grooves extending from` end to end for receiving the adjacent portions of the spring sections and formed of substantially the same Width as said portions, a projectingsocket secured to the free endof one of` the engaging sectionspandaprojection or spur secured to the free end'of the other engaging section and'movable Withinthe socket, substantially as set forth.

5l In a hue cleaner, the combination of a shank,spring sections having corresponding extremities fixed to theshank and their opposite extremities separated" and independently movable, andengagingsections secured to the spring sectionsand` having their centralportions formedofgreater thickness than `their extremities,said` sections having their inner faces formed with recesses or grooves for receiving the spring sections, their adjacent edges provided Withinterlocking shoulders and their` outer faces provided` with roundingshoulders, substantially as and for the purpose set forth.
